Digital Design, 2E
March 2010, ©2011
Unique with its RTL-early organization, Vahid's text supports instructors wishing to develop strong design skills in their students. The emergence of parallel processing, multicore processors and FPGAs are blurring the lines between hardware and software and fundamentally altering the way digital design and design logic should be taught. Vahid's RTL-early approach better assists students in grasping the essential design fundamentals before digging into specific details of design optimization.

· HDL Neutral Synthesizable VHDL, Verilog, and SystemC coverage all appear in the last chapter, with subsections corresponding to earlier chapters, allowing early or late HDL introduction, without cluttering main concepts.
· Appropriate emphasis on RTL. Topic coverage naturally leads to register-transfer-level (RTL) design, which is covered substantially. Comparisons between custom digital circuit and microprocessor implementations provide a modern perspective.
· Modern coverage of optimization and tradeoffs. Tradeoffs are introduced alongside optimization, at all levels of abstraction (not just gate level), and cleanly distinguished from basic design.
· Bottom-up description of field-programmable gate arrays (FPGAs). FPGA coverage shows precisely how circuits can be mapped to lookup tables and switch matrices using bitstreams.
